Each year, Consumer Reports ranks all manner of U.S. wireless carriers based on customer satisfaction in a number of different categories. AT&T ranked dead last in the customer satisfaction survey for the third year in a row. It was hit with the worst rankings for any major carrier in value, voice quality, and customer support.

However, the wireless carrier was ranked at the top of Consumer Reports' 4G network ratings. AT&T's customers complained of the least 4G-related problems of subscribers on any of the services.

Verizon Wireless has the largest 4G-LTE network in the United States with service in over 400 markets. AT&T's coverage is much smaller serving only 100 markets, while Sprint is much further down the list with only 40 4G LTE markets in the US.

Verizon once again took the top spot in overall rankings for major carriers in the U.S., outscoring second-place Sprint by six points in the Consumer Reports survey. T-Mobile landed in third place with AT&T a bit behind.

It's also interesting that smaller regional carriers including Consumer Cellular, US Cellular, and Credo all ranked ahead of the large national carriers in the Consumer Reports survey. Even prepaid carriers such as TracFone and Straight Talk scored better than the major nationals.
